The only way to solve the science publishing problem is from the top down: lean on scientific funding agencies for them to mandate results must be published in an open access journal. Take it a step further and say none of this "pay-us-super-extra-money-on-top-to-open-your-article-up-early" garbage either.
Hesitation from many scientists to publish in open access is that many full open access journals are not as popular and thus you lose some impact or credibility to the works when publishing in them. But if everyone is forced to migrate to open access, that will go away--perhaps with a few years of turbulence.
Otherwise, the behemoths like RELX and Wiley will endlessly pursue any sort of effort to open up their copyrighted material (and rightly so within their legal rights), just like the RIAA and music sharing.
